Study on the Performance Outcomes of Elite Track Athletes Competing at Varying Altitudes

Many high level performance athletes train at altitude to improve their performance when they race or compete at sea level, but more often than not, if they haven’t been training at a higher altitude for several weeks before competition their performance will ultimately suffer. However, some events suffer more than others. It’s known that power and…

Does Sodium Supplementation Help Avoid Dehydration While Running in the Heat?

Athletes have been consuming sports drinks and supplements for year to help avoid dehydration and the consequences that come with it. It’s often been debated if sodium and potassium supplements within sports drinks or simply taken by themselves can help preserve an athletes plasma volume, prevent dehydration, and maintain body weight while competing at high…

Aerobic Capacity and Hematological Response to Exercise: A study on school-going regularly exercising boys in two different air pollution zones.

As humans were given such a wonderful gift and opportunity to be able to call such a beautiful place our home. In an ever-growing industrial society, one like the world that we live in, one of the most extreme problems we face daily is environmental pollution. It is rather easy to imagine one breathing in…

Circadian Disruption and Remedial Interventions: Effects and Intervention of Jet Lag for Athletic Peak Performance

Peak efficiency requires athlete’s minds and bodies to be in sync, therefore jet lag can have potential serious effects on athletes performance. Crossing time zones (eastwards or westwards) causes a desynchronization of an individual’s circadian rhythm. The primary function of the circadian rhythm is to allow the body to adapt to various external environments. Jet…

Effects of Post-Exercise Honey Drink Ingestion on Blood Glucose and Subsequent Running Performance in the Heat

To date, the possible role of carbohydrate contained in honey during recovery after exercise has yet to be investigated.  This particular study was proposed with the use of Acacia honey produced in Malaysia which hold 31.2% of fructose, 22.9% glucose, 3.3% of maltose, and 9.9% of sucrose, and it also contains 13 milligrams of sodium…

Jet-Lagged Baseball Teams Suffer Disadvantage

Bradley Lanier 3/29/16 Jet Lag Effect on Baseball This article discussed how Jet-Lag could ultimately effect a major league baseball game. The researchers suggested that, given the data, a team that has to cross three time zones to play a game has a 60% chance of losing. The collected data used in this study spanned…

Anaerobic Performance When Re-hydrating with Water or Commerically Available Sports Drinks Following Prolonged Exercise in the Heat

Article Review The purpose of this study was to examine the effect of commercially available sports drinks on rehydrating capacity and anaerobic performance following exercise in the heat. Other variables of interest included drink palatability, thirst, feeling of stomach fullness, and urine output during exercise. The sample group consisted of seven endurance trained cyclists. Prior…

Effects of Heat and Humidity Levels on Aerobic and Anaerobic Exercise

A study by Zhao et al. in 2013 explored the effects of three different environmental conditions on aerobic and anaerobic performance. There were nine Chinese, male, trained track and field athletes, with the average age of 21.6  ± 1.2 years and similar anthropometrics. The study was in the spring to prevent any natural heat acclimatization that…

Time course of natural heat acclimatization in well-trained cyclists during a 2-week training camp in the heat

Studies how shown that acclimatization to heat takes time and cannot happen all within one day. It is shown that physiological adaptations and their correlation with performance can improve once they’re acclimated to that environment. Certain factors that affect heat tolerance are core temperature, skin temperature, and sweating capacity. The study was conducted within a…

Electrolyte supplementation during severe energy restriction increases exercise capacity in the heat

This study was done by Lewis James, Stephen Mears, and Susan Shirreffs to examine the effects of electrolyte supplementation during severe energy restriction on exercise capacity in the heat. The participants were nine healthy males with a mean age of 25 years old. All of the participants were physically active. They participated in this study…

Biorhythms and Predicting Death

https://drive.google.com/a/g.cofc.edu/file/d/0B6_FHBfuogQdNzBkbXdoNzY5N2RZWWROLXFrakJScGVPWG1v/view?usp=sharing   The article I chose to research was titled “Validity of Biorhythms for Predicting Death” and dealt with the way that natural biorhythm cycles may or may not affect life expectancy.  Biorhythm theory suggests that there is a 32 day physical cycle, a 28 day emotional cycle, and a 33 day intellectual cycle which…

Air Pollution and Lipid Profiles in Athletes Versus Sedentary Adults

One of the more predominantly motivational reasons to exercise is to decrease the risk of cardiovascular and respiratory diseases, among staying fit, losing weight, etc. It is widely known that an increasing amount of air pollution has become a major health problem for individuals worldwide.  Something to be considered is the risk exercising in polluted…
